UNITED srA'r JOHN J. LYTH, OF VALLEYFIELD, QUEBEC, ANADA APPARATUS FOR AIID PROCESS OF PZLENG ROED CLQTJH 6N A CIRCULAR AREA Application filed September 13, 1926, Serial No. 135,127, and in Great ritain September 4, 1925.

This invention relates broadly to improvements in apparatus for and process of piling roped cloth on a circular area, for example, in a cylindrical kier, and relates more particu- 5 arly to improvements in the apparatus disclosed in my former Letters Patent No. 1,528,-

065 granted 3rd March 1925.

The primary object of the invention is to provide a cloth piling machine materially 10 amplified in construction, of less weight and capable of being manufactured at smaller cost,all as compared with apparatus previously identified.

A further object is to provide a machine so lonstructed and arranged that it projects only a minimum distance into a kier, thus permitting the cloth to be piled to a maximum depth in the kier.

A still further object is to provide in a -nachine oi the type embodying a chute swing ing or oscillating in vertical planes, means for automatically controlling the swing of the spout to ensure delivery of the cloth at the wall of the kier at all levels and yet capable of manual control.

Another object is toprovide in a machine of the type last mentioned a chute so arranged that in swinging it does not exert any lifting efi erxt on the cloth.

Still another object is to provide a machine of the "ype embodying a chute swinging in vertical planes, which will pile cloth accurately along a predetermined path, avoiding a constant retracing oi the path, and maintain the top oi the pile approximately level, or which will in the course of filling a kier automatically average up departures from level piling so that, when the l-Iier is filled, the top of the pile will be level or desirable. v

Various other objects and advantages additional to those disclosed in my former patent may be ascertained from the following description and accompanying drawings.

In circular cloth piling machines formerly devised by me, the cloth has been passed through a revolving gointed conduit including a vertical rotatable portion swinging a lateral extension in a horizontal plane. This exslightly mounded in the centre, which is tated projection of the conduit for an appreciable distance downwardly into the kier.

According to the present invention, a revolving conduit is employed embracing only two sections, namely, an upper vertical section and a lower section or chute telescopically related to the upper section and swinging in vertical planes. The conduit is supported and revolved by mechanism similar in its essentials to that disclosed in my former patent already identified, but the manner of operatin g the conduitis radically different.

If a normally vertical chute'swings or oscillates from a horizontal axis near its upper end, it" will be apparent that as the chute swings outwardly its lower end will rise and, as it approaches horizontal position, will exert a gradually increasing lifting effort on cloth passing through it. This materially increases the power required for operation, invites clogging with cloth at the outward extreme of movement and, what is most undesirable, necessitates a'considerable downward projection of the chute into the kier in order that the necessary amplitude of swing may be obtained without the chute striking the shoulder of the kier. I have obviated all these disadvantages by so arranging the mechanism that the chute swings from a centre descending during the outward swing and vice versa, with the result that the con ditions before noted are reversed, that is, the lower end of the chute descends it moves out. Three results are obtained: the chute when vertical has its least downward projection into the hier ;'there is no lilting effect on the cloth; it is possible for the chute to be moved bodily toward the wall of the kier without accompanying descent into the kier;

the chute by a current of liquid and is discharged at varying angles according to the position of the chute in its swing. The cloth falls in an approximately parabolic line or trajectory as would water from an inclined nozzle or a projectile from a gun. As the level of the pile rises, it is necessary to increase the angle at which the cloth is directed and this is automatically accomplished by simple means operated at each movement of the chute to slightly shift a limit stop en gaged by the descending chute for operation of the reversing gear.

Referring more particularly to the drawin s, 11 designates a circular frame or base d signed to be disposed axially vertical and provided at suitable intervals with lugs 12 in which shouldered pins 13 are mounted with provision for adjustment radially of the base. These pins are adapted to rest upon the .ip of a lzier ll with the shoulders engaged within the lip so as to centre the machine in the kier mouth. The lugs 12 also provide means for the attachment of cables 15 to suspend the machine from an overhead truck. The circular base- 11 is provided with an inwardly projecting flange 16 presenting at its inner edge an upturned rim 1'? immediately outside of which is a bearing surface 18. A worm toothed ring gear 19 is disposed within the base approximately co-anial therewith and is provided on its lower side with a pair of flanges 20 and 21 embracing between them the rim 1'? of the base whereby the worm gear is held against radial movement within the base. The flange 20 rests on the bearing surface 18 thereby supporting the worm gear. A. worm 22 is mounted in any suitable way on the base and meshes with the ring gear 19. The spindle of this worm is driven by a chain 23 or other suitable means from a motor 24 mounted on bracket 25 carried by the frame. An internally toothed gear or circular racl 26 is fixedly mounted in the base above the worm gear and projects over the worm gear, thereby to hold the same against upwardv movement out of the base.

The ring gear 19 forum a rotating support for the mechanism hereinafter described which constitutes the conduit and the o n-vrating means therefor.

lnward projections 27 from the ring gear carry a pair of main side frames 28 connected thereto by brackets 29 or other suitable means. These frame plates 28 extend above and below the ring gear as clearly seen and at their upper ends are rigidly connected to and rigidly support a preferably cylindrical stationary conduit section 80, which is located in axial alignment with the base and ring gear and which extends downwardly to approximately the level of the ring gear, as clearly shown in Figure 1. A lower conduit section or chute 32 is provided which, at its upper end, encircles the upper section 30. The upper end of the chute 32 is so formed that the chute may be freely n'loved up and down in an arcuate path relatively to the vertical upper section. The lower end of the chute which is at all times below the upper section is tapered to an outlet of suitable size and shape, and the lower wall of the chute is shaped to facilitate passage of cloth thereover. The chute is in part su mortcd and is at all times uided in its movement by upper and lower lOilGl'S 33 on both sides thereof ongaging upper and lower tracks or slots 3% and 35 respectively. The rollers may be mounted on the chute and the tracks formed in the frame plates 28 as shown. or vice versa. These slots may be variously shaped according to the exact path and speed variations of move ment desired, but the form illustrated has been found suitable and is as follows: l lach upper slot is approximately parabolically curved, the radius being least at the top and. gradually increasing toward the bottom where it is greatest. It will be understood that the curvature may include one or more circu arly curved portions of appreciable length or may be a succession of circularly curved portions. Each lower slot is mainly ture of the upperand' lower slots is the same and the slots are arranged substantially in alignment, so? that the reverse-1 y curved upper portions: of the lower slots ext-end outwardly of the: general line of the slots. The slots are preferably so: located that the upper and lower ends of each upper slot lie in a single approximately vertical line, while the lower portion of each lower slot" lies in an approximately horizontal line, the whole as shown in Figure 1. It will be readily seen that as the; chute'32 rises and falls, the engagement of its guiding rollers 33 in the slots 34 and 35-wi ll cause the chute to move in an arcuate path. The special formation of" the slots lifting efie-rt on the cloth. This feature can be best appreciated by comparison of the movement indicated in Figure 2 with what would occur'if-the chute swung from a fixed centre at, say, the upper guide rollers 33. If

Y the centre o.f"oscillation was fixed, it would meshing with the internal gear 26.

be necessary, in orderfor the chute to swing under the shoulder of'a kier, to have the fixed centre-so low that the end of the chute when in. the'kier" axis would be much lower and would prevent piling cloth in the upper part of the kier. disclosed, it is possible to produce a slightly 'mounded piling extendingat the axis almost up the; neck of thekier, so that the capacity of the kier isxutili'zed to themaximum. The peculiar movement of the chute enabling it to reach'under the shoulder of the kier has the effect of extending control and support secured by brackets 37 to the lugs 27 of the ring gear and carry the chute operating means. Atransverse member 38 is connected between; the plates 36' a short distance above the internallgear 26 and serves as an upper bearing for a vertical spindle 39, the lower end of which bears in a lug 40 of the ring gear. Between its two bearings, the spindle 39' has rigidly connected to it a pinionr 411 e upper end ofthe spindle has rigidly connecte'dito it a bevel pinion 42 meshing with a pair of'bevel, pinions 43 and 44 revolubly mounted on a shaft 45 journalled in bars 46 connected between the frame plates 36.

A sli'dingfianged clutch sleeve 47 is splined With the. construction hereinv to the shaft 45' and is adapted to mesh with either of the gears 43 or 44. Each end of the" clutch sleeve has preferably a single diametrically disposed rib'or' tooth 47 adapted to I mesh respective-lyin diametrically cut grooves 43 and 44 of the gears 43 and 44 respectively.

It will be noted from Figure 8* that the gear 43, which is the chute lifting gear, has only one slot 43 while the gear 44 which'isthechute lowering gear has a plurality of slots 44 mtersecting at the centre of the gear. The purpose of the different numbersof slots in the gears 43 and 44 is to provide as muchlost motion as possible at one reverse in order to prevent the lower end of the chute exactly retracing its former path and to minimize lost motion at the'other reverse, in order to reduce asmuch as possible the dwell of'the chute in the axis of the kier. V

The forward or outer end of the shaft 45" has fixed thereto a sprocket 48" connected by a chain 49 with a similar sprocket 50-, fixedly mounted on a shaft 51 journalled in bars 52" connected between the upper ends of the frame plates 36. Any suitable form of tensioning device, such as the laterally adjustable idler sprocket 49, may be provided for,

the chain to minimize the lost motion or back lash, which must be taken up at each reversal. A shaft 53 is journalled in the frame plates 36 at right angles to the shaft 51 andis driven from the shaft 51 by worm gearing 54. The

shaft 53 carries a pair of sprockets 55- over,

which pass chains 56, corresponding ends of which are connected in any suitable way .to the upper end of the chute 32... Most conveniently, the connection is established by.

means of links 57 pivoted on. the centre pins The clutch is operated by a: spring actuated lever or toggle including a lostmoti'on device, the whole shown in detail in'Figures '6' and 7. The clutch lever consists of two parts 59 and 60, each loosely mounted on a shaft.

upper end is embraced between the side mem- V bers of the part 59 and is bifurcated to receive between the bifurcations 62 thereofthe cross bar 63 of the H'-shaped part 59. The

space between the bifurcations 62* is such:

that there is considerable lost motion per mitted, as will be readily seen In Figure 6.

4 The lower end ofthe lever part 60 isjawed 65. By partial rotation of the shaft to embrace the clutch sleeve 47 and carries pivotally mounted shoes 64 running between the sleeve flanges. A shaft 65 is journalled between the frame plates 36 above the shaft 61 and has rigidly secured thereto an arm 66 slidable through a block 67 trunnion-mounted between the upper ends of the side members of the lever part 59. A helical spring 68 is compressed between the block 67 and shoulder on the arm 66 adjacent the sh ft e arm 66 may be moved from the inclined position shown in full lines Figure 6 nearly to the neutral position shown in broken lines, without producing any movement of the lower end of the clutch lever, owing to the travel of the cross bar 63 between the bifurcations 62. This permits the jointed lever mechanism to be moved through the neutral position to an opposite inclination before the clutch is unmeshed, for example, from the pinion 43, so that the spring will exert itself to throw the clutch into mesh for example with the pinion 44. In other words, the lost I motion connection permits the mechanism to move through the neutral position, even i f the clutch should not mesh when thrown, so that when the teeth of the clutch and grooves of the pinion do come into meshing: relation, the spring mechanism will be sufficiently beyond the neutral position to be capable of effecting the desired meshing. This mechanism renders the clutch infallible in operation as is absolutely necessary.

The shaft 65 is rotated as is necessary to shift the clutch by the movement of the chute 32 in the following manner. An arm 69 is rigidly secured to the shaft and carries at its extremity a rod 70, upon which are mounted upper and lower adjustable steps 71 and 72 respectively. Preferably. the rod '70 is threaded and the stops 71 and C" 2 are nuts cooperating with the threads of'the rod. A. slide 73 is mounted on the rod between the upper and lower stops and is pivotally connected to an operating lever 7 4 at a point intermediate the ends thereof. This lever is fulcrumed at one end at any suitable point. for example, on the shaft 61 and is connected at the oppositeend of the chute 3;, for ample, to the centre pin on an upper roller 33. At the fulcrumed end, the lever 74 slotted as at 75 to compensate for the location of the shaft 61 eccentrically with respect to the curvature of the slot 34, which determines the movement of the lever. The lever 69 is preferably provided with a counter-balance weight 7 6 on the opposite side of the shaft 65 from the mechanism just described, so to render the actuating; mechanism as sensitive as possible. As the chute moves up and dow it shifts the slide 73 on the rod 70, bringing the same into contact with the stops 71 and 7 2 alternately and ti ereby imparting; longitudinal movement to the rod, which then opcrates the arm 69 to rotate the shaft 65 and initiate shifting of the clutch, so as to change tie direction of movement of the chute.

It has been stated that the amplitude of movement of the chute 32 is automatically increased as piling progresses. In each upward movement of the chute, the rollers 33 travel to, or nearly to, the upper ends of the slots 34 and 35, so as to bring the lower end of the chute into, or very close to, the axis of the kier and therefore vertic: lly beneath the upper section 30. The exact limit of upward movement and therefore of the approach of the chute end to the axis of the kier is determined by adjustment of the upper stop 71. Vi hen filling of the kier is commenced, the angle subtended at the piling mechanism by the radius of the kier at the bottom thereof is comparatively small and but little movement of the spout is required to direct the cloth at such an angle that its trajectory or line of travel (indicated in Figure 10) will extend to the wall of the kier. Tn order to limit the angular movement of the chute to obtain only this degree of lateral projection, the lower stop 72 is positioned well upon the rod .70. The lower stop 7 2 is held against rotation by a link 77 pivotally connected thereto and running" in a guide 78 (Figure 3) carried by one of the frame plates 36. llfechanism is provided operating automatically to slowly rotate the rod, so that the irrevolublc nut 7 2 or bottom stop gradually shifts down as the piling progresses, allowing the chute 32 to slightly increase its amplitude of anyrular movement at each descent. This mechanism comprises a pawl 79 adjustably mounted on the slide 73 by means of a threaded spindle 30 and nut 81, the said pawl meshing; with a ratchet wheel 32 lined on a spindle 83 and connected by mitre gears 84 with the rod. 0 which for the purpose is journalled in a stirrup 85 carrying the spindle 83. This stirrup serves to connect the rod to the arm 69. With the pawl to the right of the rod as shown, in the final part of each upward movement of the chute 32, the pawl 79 rotates the ratchet wheel 82 a fraction of a revolution de termined by the vertical adjustment of the pawl relatively to the slide 7 3 and this rotation is communicated as already described to the rod 70, causing the same to partially rotate within the irrevoluble stop nut 72, so that the same is shifted slightly down on the rod. The pawl may be placed to the left of the rod, in which case rod. rotation is effected on commeneement of the downward movement. ll rebound pawl 86 is carried by the stirrup to hold the ratchet wheel 82 against reverse rotation when the pawl 79 trails over it. A hand wheel 87 is provided on the spindle 83 to permit of manual adjustment of the lower stop 7 2 by rotation of the spindle. When the stop 7 2 is at its lowermost position, the rollers 33 travel substantially to the lower ends of lowering of the chute.

the slots 34,'thereby permitting the chute. a maximum amplitude of movement and a maximum lateral reach under the shoulder of a kier, so that cloth will be directed to reach the wall of the kier only slightly below the level of the end of the chute. By slightalteration in the shape of the slots 34 and 35, the chute may be caused toswing more nearly to horizontal position than shown, but it will be understood that the amplitude of chute swing is governed by the length of neck of the kier with which it is to be used.

In order to supply liquid for lubricating and loading the cloth to facilitateits movement' through the conduit, a stationary funnel '88 is mounted upon the upper end of the conduit section relatively revoluble with relation to the section, so that the same may rotate under the funnel, which is held stationary by its liquid supply pipe 89 clamped downwardly into the conduit and provided with a series of apertures 92 leading from the annular channel90- These apertures are so disposed as to compel discharge of the fluid in the form of a series of jets which converge to the axis of the conduit section 30 at a point below the funnel 88. A. rope of cloth passing through the conduit is caught by the downwardly converging ets of liquid, which beat upon it from all sides, thus causing a rapid and thorough impregnation of the cloth as well as a loading thereof. The converging jets also serve to centre the cloth in the conduit and further provide a film of liquid outside the cloth, which acts to lubricate or float the same through the chute. By this means, the cloth may be passed through the conduit at very high lineal speed without danger of blocking even when the chute 32 is at its maximum inclination.

Briefly described the operation of the machine illustrated is as follows :'assuming the chute 32 to be drawn up to the maximum extent and the clutch properly positioned for The motor drives the worm 22 which in turn slowly rotates the ring gear 19 and with it all the mechanism mounted on it. The pinion 41 is by rotation of the ring gear caused to travel over the rack gearing and worm gearing, rotates the sprockets 55 in clockwise direction, so that the chute 32 is lowered. The upper and lower guide rollers 33 thereof travel down in the angle determined by the position of the chute 32 and travels through a curved path or trajectory between the chute and the kier bottom or cloth already piled in the kier. With a ratio of gearing such as shown, the machine rotates several times about its axis, while the chute is descending orascending. The result is that the cloth is directed so that it falls in an approximately spiral line. Owing to the curvature of the upper ends of the slots 34, 35, the upper end of the chute is at first moved to the right, while the lower end is moved sharpl and quickl to the left, as will be seen from i igure l. n the intermediate part of the movement the rollers are travelling in the medial portions of the slots and the chute swings less sharply. In the final part of the descent, the lower rollers run sharply to the left in the bottoms of the slots 35, while the upper rollers drop nearly vertically in the lower parts of the slots 34, so that the chute moves much more to the left than it does downwardly. This formation of the slots 34 and 35 causes the angular speed of the chute (in its arcuatepath) to be greatest at the commencement of its descent and to diminish as it descends. The effect produced by the compounding of this movement with the rotation of the whole machine is that the cloth is laid in a roughly spiral line, the inner turns of the spiral being spaced further apart than the outer turns, which are adjacent the wall of the kier. The lineal speed of the cloth is materially greater than the lineal speed of the lower end of the chute travelling in its spiral path, with the result that the rope of cloth instead of being stretched smoothly is bunched up, forming a mound or pile of spiral shape. hen the chute reaches the extremity of its downward movement, the mechanism reverses as already described and the chute commences to rise. The ratio of the gearing is preferably such that the end of the chute does not exactly retrace its original path but follows a similar path slightly out of register with the former, so that the cloth piled during the inward swing of the chute tends to fill spaces between the turns of the spiral of cloth first made. This motion continues. Each time the chute rises it rotates the rod to a suitable extent, thus causing thestop 72 to move down on the rod and permit a slightly greater descending movement the next time. In this way, the angular movement of the chute in its arcuate path is gradually increased as the piling level rises toward the machine. At the same time the increased descending movement enables the chute to reach slightly further under the shoulder of the kier and to approach more nearly to the horizontal. By reason of these two occurrences, the chute is enabled to so direct the cloth that at the exreme of movement the cloth will fall at the periphery of the kier, The net result is that the various LAO layers of cloth laio 1 the hicr average one another and the to ayer is approximately horizontal or slightly raised in the centre. (living to the small vertical. distance rcquirec for operation 01" the machine, cloth may be piled in the hier nearly up to the shoulder.

l Vhile I have described and illustrated one embodiment of my invention, I wish it to be understood that numerous modifications of detail may be made without departing from the spirit of the invention, particularly in the ratio of the speed of rotation to the eed of chute swing. By relatively increasing the speed of chute swing, the spiral traced by the piling cloth may be caused to extend from the centre to the wall of the kier in less than one revolution of the machine and, in cases where the speed of the cloth is variable, shorter spirals are preferable.
